Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609784, here are decompositions:

11 + 8609773 = 8609784
31 + 8609753 = 8609784
97 + 8609687 = 8609784
101 + 8609683 = 8609784
107 + 8609677 = 8609784
137 + 8609647 = 8609784
163 + 8609621 = 8609784
167 + 8609617 = 8609784

Showing the first eight; more decompositions exist.
